 Each channel supports 50\textOmega~terminations, individually controllable using DIP switches. Outputs tolerate short circuits indefinitely. Both cards are capable of a minimum pulse width of 3ns.
 
-Note that isolated TTL cards are less suited to low-noise applications as the isolator itself injects noise between primary and secondary sides. Cable shields may also radiate EMI from isolated ground. For low-noise applications, use non-isolated cards such as 2238 MCX-TTL or 2245 LVDS-TTL.
